Limit Your Cell Phone Radiation Exposure


  • Exposure to cell phone radiation is a constant for most of us. Our phone is with us all the time. Cell phones emit radio-frequency (RF) energy.
  • When you hold your cell phone next to your head or wear it on your body, you can absorb over 50% of the transmitted RF energy.
  • So take precautionary steps to protect yourself and minimize your exposure
  • If you don’t have a Pong case yet, or one is not available for your particular mobile device, the following tips you can do in your daily life to help protect yourself and limit your exposure to cell phone radiation.

Avoid Body Contact

  • Follow the phone manufacturer’s warnings found in your owner’s manual and avoid using or carrying your cell phone against your head or body at all times
  • At least 10mm of space between you and your phone.
  • shouldn’t keep it in your pocket .

Text More

  • Whenever possible, text rather than talk.
  • When texting your phone will be likely held in your hand and further from your body.  
  • This distance creates a much larger buffer between you and the powerful near field radiation from the phone.

Use Speaker Mode or a Wired Headset

  • If a call must be made, use the speakerphone or a wired headset.
  • When holding the phone against your head for a call you are increasing the amount of radiation your head will be absorbing.
  • The speaker or wired headsets reduce the amount of near field radiation you are exposed to.

Shorter Calls

  • Limit the length of your cell phone conversations.
  • Less time talking with a phone against your head equals less radiation going into your body.  
  • Use a corded landline phone if available.
  • Do not use a cordless phone for long conversations.

Limit Kids Cell Phone Use Time

  • Children should only use cell phones for emergencies or strictly in speaker mode at a safe distance.
  • A child’s body is still developing and cell phone radiation penetrates a child’s brain more deeply than an adult brain.

Switch Sides of Head When Talking

  • Switch sides regularly during a cell phone call to reduce radiation exposure to just one side of your head.
  • Most of us use the same hand all the time to hold the phone when we talk.
  • Try to switch to your other hand and it will help so that one side of your head doesn’t always get all the radiation.

Avoid Use When Low Signal

  • Avoid using your cell phone when the signal is weak or when moving at high speed, such as in a car or train.
  • These cause mobile phones to increase their transmitting power in an attempt to connect to the nearest cell tower.
  • You get more radiation and your battery drains faster under these conditions.

Wait For Call Connection

  • When making a call, wait for the call to connect before placing the phone next to the ear.
  • The phone emits the most intense radiation during the initial connection, then lowers its power once a connection is established.

Use Airplane Mode

  • Turn your cell phone off or put it in airplane mode when not in use.
  • If you must leave your cell phone on at night, keep your cell phone away from your head and body while you are sleeping.
  • Your phone continues to emit radiation even when you are not making a call.
